Title: A method for removing water from deposits formed from aqueous dispersions of rubber or similar vegetable resins
IPC: F26B5/14
Filed: 1928-10-08
Abstract: 298,483. Anode Rubber Co., Ltd., (Assignees of Szegvari, A.). Oct. 6, 1927, [Convention date]. Indiarubber, preparation of.-Articles made by depositing rubber &c. from aqueous dispersions are partially dried while still on their deposition bases by applying thereto a pervious material which exerts a compacting pressure. For example, a rubber layer a deposited on a mandrel b is wrapped with a fabric strip f by mounting the mandrel between a tail-spindle c, and a driving- head d, and feeding the strip f at an inclination under tension, until the rubber is covered with one or more layers of fabric. The fabric is removed, leaving the rubber still containing some liquid, but sufficiently compacted and dried to enable it to be stripped from the mandrel. Specification 308,626 is referred to.

Abstract: 694,801. Electric tests and measurements. GENERAL ELECTRIC CO., Ltd., and BLOCH, A. Nov. 27, 1951 [Nov. 27, 1950], No. 28979/50. Class 37. An A.C. impedance bridge comprises inductive ratio arms consisting of a brass bar 21 (Fig. 2), which at 10-100 mc. may be considered as purely inductive, having a variable tap 33, the unknown impedance 8 with a parallel variable condenser 7, and the fourth arm comprising a resistor 5 in parallel with another variable condenser 6. The detector comprises as shown a galvanometer 24 and half-wave rectifier 23, or may be a CRO fed through an amplifier. The apparatus is contained in a box 32 (Fig. 3), the tap 33 being controlled by a knob 34 also moving a pointer 35 over a scale 37 which is calibrated in terms of the ratio n of the ratio arms 21. Control wheels 38, 39 associated with calibrations 43, 44 enable condensers 6, 7 respectively to be adjusted for balance. The capacitance C 1  of condenser 6 is adjusted by wheel 38 so that C 1 /n is constant, as determined by a second scale 47 associated with pointer 35, giving the required reading for calibration 43. Balance is then obtained by adjusting condenser 7 only, and the shunt capacitance of the unknown impedance 8 may be read directly on calibration 44. An additional scale 48 may be used to cover a different range of values. The inductance 21 may be increased by adding external inductance elements, or the resistance 5 may be changeable to other values. Specification 694,802 is referred to.

Title: Improvements relating to electrically heated molten salt baths used in heat-treatment furnaces
IPC: C21D1/46
Filed: 1948-11-11
Abstract: 651,233. Electrically heated salt baths ; electrodes. MOND NICKEL CO., Ltd. Nov. 11, 1948, No. 29374. Convention date, Nov. 13, 1947. [Class 39(iii)] In order to prevent corrosion of metal electrodes, at least 100 parts per million of chromate are maintained in the salts of a molten salt bath used in the heat treatment of metals and heated by A.C. passing through the bath between metal electrodes at an average current density of at least 7 amperes per square inch of electrode area exposed to the bath. The chromate content of the bath is preferably 500 parts per million but may be 2,500 parts or more per million the chromate concentration being increased if the carbon content of the steel being treated is small. Any chromate soluble in the bath may be used, preferably on alkali metal chromate or a dichromate. The baths used for hardening steel consist of one or more chlorides of the alkali and alkaline earth metals, but fluorides and carbonates of these metals which are stable at the operating temperature may be present. Baths comprising 56 per cent potassium chloride are used at temperatures of 1,300 -1,800‹ F., or a mixture of 77 per cent barium chloride and 23 per cent sodium chloride is used at 1,800‹ F.- 2,200‹F. One per cent of sodium carbonate may be added. These baths are not strongly carburizing or decarburizing in their action on the steel under treatment. The electrodes are alloys consisting of chromium (5-35 per cent) with iron, nickel or cobalt and preferably comprise 10-22 per cent of chromium, 7-82 per cent of nickel and up to 80 per cent iron and include stainless steels. The chromate appears to form a protective film on the electrodes, but as the chromate is rapidly consumed by electrode sludge, the latter is not allowed to accumulate in the bath. The usual rectification or de-oxidation treatment of the bath is employed and as the chromate has an oxidising effect, cyanide or the like having a reducing effect may be added. The chromate content of the bath is determined by matching its colour with known standards. With baths containing 81 per cent calcium chloride and 19 per cent potassium chloride, continuous replacement of chromate may be required. The electrodes are rods of preferably square cross section and current passes between closely spaced pairs. A current density of up to 41 amperes per square inch is mentioned.

Abstract: 815,749. Hypodermic syringes. PRODUFARMA LIMITADA. Oct. 18, 1955, No. 29645/55. Class 81 (2). A hypodermic syringe is provided with a hollow piston in which medicament is stored and which has a diaphragm which is pierced to allow the medicament to pass into the syringe barrel. The piston is formed as two sleeves 3, 6, telescopically arranged one within the other and mutually adjustable by a threaded engagement of their mating surfaces. The lower end of the outer sleeve is closed by a rubber plug 4 and the piston assembly is made liquid-tight in the barrel 1 by a ring 7. Medicament is preferably carried in a capsule 8, retained within the inner sleeve 6 and having a piercing needle 15. When required for use, the two parts of the piston are screwed towards each other so that the needle 15 pierces the plug 4 and allows the medicament to be passed into the barrel of the syringe as the plunger is drawn back. If the lower part of the barrel 1 has been previously filled with a solid or liquid medicament, mixing now takes place and produces a compound ready for injection. The inner part 6 of the plunger is now screwed outwards to withdraw the needle 15 from the plug 4 and, after the closure cap 5 has been replaced by a standard needle the syringe is ready for use.

Abstract: 1,026,667. Valves. BASTIAN-BLESSING CO. July 26, 1963 [Aug. 1, 1962], No. 29680/63. Heading F2V. A valve controlling the flow from a tank 17 comprises a valve 12 connected to a flange 10 of the tank and to a pump 14. The valve 12 comprises a body part 22 having an outlet at its lower end and a valve seat 30 at its upper end. A cylinder 42 is screwed on to the body 22 and houses a piston portion of a valve closure member 46, the cylinder being provided with inlet ports 44. The valve member is urged towards the closed position by a spring 66. A control valve 78 in the valve piston has a closure element 86 and is urged to the closed position by a spring 84. The valve 78 is guided by a boss 80 in an aperture 82 of a wall 62 which extends partially across a bore 56 of the piston. The control valve is connected by a rod 120 to a piston 114 which is subjected to the pressure in a space 115 supplied through a pipe 108 having a restricted connection 112 to the valve body. The pipe 108 is connected to the outlet side of pump 14. A manually rotatable rod 133 is connected to the rod 120 by a pin 118 and has a mark 139 on the end which indicates the position of the rod 120 and hence the valve piston. When the pump 14 is not running the piston valve is closed and the liquid in the tank passes through a filter 34 a radial passage 88 and bore 56 to the upper side of the piston and also through a valve by-pass passage 144, controlled by a throttle 154, to the downstream side of the piston valve, to prime the pump. The pressure in space 115 is also at the pressure on the downstream side through restriction 112. When the pump is started pressure is fed to space 115 to raise the piston 114 which first opens the control valve to allow flow from the top of the piston and the control valve then abuts the partition 62 and further movement of the piston 114 opens the piston valve 46 to allow flow from the tank. The opening of the piston valve is also assisted by the liquid in the tank acting on the lower face of piston portion 48. When the pump stops, the valve closes with leakage from the space 115 through restriction 112. The valve may be opened manually by rotation of rod 133. The tank may be filled by a connection to the valve body on the downstream side of the piston valve.
